Abstract: 446,316. Coin-freed article-delivery and game apparatus. BINKS, M. J., 1134, North Kilbourn Avenue, Chicago, U.S.A. June 26, 1935, No. 18330. [Class 27] Articles to be vended are stored separately on an annular turntable 10 within a display compartment 12 of the apparatus. To operate, the purchaser first rotates a knob 21 until the number 94 on the turntable, corresponding to the article desired, is registered by an indicating dial 48 geared to the shaft 22 of the knob, whereupon, after the insertion of a coin, the turntable 10 is rotated by an electric motor 39 to bring the selected article before an ejector 18 carried by a boom 19, which then rotates upon its shaft 51 and, subject to the hazards inherent in the apparatus, delivers the article through an opening 15 in a stationary plate 13 to a delivery opening 80 in the front of the apparatus. For controlling the operation of the turntable motor 39 and an electric motor 57 operating the boom 19, there is provided a commutator switch comprising an arm 24 secured to the shaft 22 having interconnected wipers 25A, 25B, 25C, 25D, 25E, engageable respectively with contact segments 26A, 26B, 26C, 26D, 26E on one face of an insulating disc 27 secured to a sleeve 30 loose on shaft 22 and connected through a sprocket chain 32 to the turntable 10. On the opposite face of the disc 27 are a series of annular contact members 28A, 28B, 28C, 28D. 28E connected respectively with the five contact segments 26 and engaged by separate wipers 29A, 29B, 29C, 29D, 29E. The contact segment 26A is gapped at 93 and controls the stopping of the motor 39 at the correct position of the turntable, and the short contact segment 26B controls the starting of the boom motor 57 when the turntable reaches this position. The contact segments 26C and 26D select the appropriate operating coil 76, 77 of a reversing switch for the turntable motor 57, which comprises a pair of mercury switches 68, 69 mounted, together with a similar controlling switch 70, on a rocking shaft 71 connected with an armature core 73 passing through the coils 76, 77. Normally, the motor circuits are broken at coin operated contacts 66 and the commutator switch contacts 25A, 26A. Upon rotation of the knob 21, the circuit is closed at contacts 25A, 26A, and the appropriate contact segment 26C and 26D engaged; subsequent closure of the contacts 66 by insertion of a coin then causes operation of the reversing switch 68, 69, if this is necessary so that the circuit of the motor 39 is closed to rotate the turntable in the appropriate direction. When the selected article arrives before the ejector 18, the gap 93 and the short contact segment 26B engage the wipers 25A and 25B respectively, which breaks the circuit of the turntable motor 39 and closes that of the boom motor 57. The shaft 51 of the boom is connected with the motor by a crank 52 and link 53, and, after one complete reciprocation of the boom, mechanism associated therewith opens the contacts 66 to stop the motor. The contacts 66 also control the circuit of a solenoid 64 which, after the insertion of a coin, is energized so that its armature 62 engages a toothed wheel 60 to prevent the shaft 22 being moved during movement of the turntable or ejecter, a slipping clutch 23 taking up the movement of the knob 21 under these circumstances.
